Abstract
BACKGROUND To explore the diagnostic usefulness of extracellular vesicles (EVs), and their subpopulations (micro-vesicles and exosomes), and microRNAs (miRNA-21-3p, miRNA-150-5p, and miRNA-26a-5p) in peri-implant crevicular fluid (PICF) of subjects with healthy, peri-implant mucositis and peri-implantitis implants. METHODS A total of 54 patients were enrolled into healthy, peri-implant mucositis, and peri-implantitis groups. PICF samples were collected, EVs subpopulations (MVs and Exo) were isolated and characterized by nanoparticle tracking analysis and transmission electron microscopy. The expression of miRNA-21-3p, miRNA-150-5p and miRNA-26a-5p was quantified by qRT-PCR. Logistic regression models and accuracy performance tests were estimated. RESULTS PICF samples show the presence of EVs delimited by a bi-layered membrane, in accordance with the morphology and size (< 200 nm). The concentration of PICF-EVs, micro-vesicles and exosomes was significantly increased in peri-implantitis implants compared to healthy implants (P = 0.023, P = 0.002, P = 0.036, respectively). miRNA-21-3p and miRNA-150-5p expression were significantly downregulated in patients with peri-implantitis in comparison with peri-implant mucositis sites (P = 0.011, P = 0.020, respectively). The reduced expression of miRNA-21-3p and miRNA-150-5p was associated with peri-implantitis diagnosis (OR:0.23, CI 0.08-0.66, P = 0.007 and OR:0.07, CI 0.01-0.78, P = 0.031, respectively). The model which included the miRNA-21-3p and miRNA-150-5p expression had a sensitivity of 93.3%, a specificity of 76.5%, a positive predictive value of 77.8%, and a negative predictive value of 92.9%. The positive and negative likelihood ratios were 3.97 and 0.09, respectively. The area under the receiver operating characteristics curve for the model was 0.84. CONCLUSIONS An increase concentration of EVs with a downregulation expression of miRNA-21-3p and miRNA-150-5p could be related with the peri-implantitis development.

Abstract
Cancer-Testis antigens (CTA) are named after the tissues where they are mainly expressed: in germinal and in cancer cells, a process that mimics many gametogenesis features. Mapping accurately the CTA gene expression signature in myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML) is a prerequisite for downstream immune target-discovery projects. In this study, we take advantage of the use of azacitidine to treat high-risk MDS and CMML to draw the CTAs landscape, before and after treatment, using an ad hoc targeted RNA sequencing (RNA-seq) design for this group of low transcript genes. In 19 patients, 196 CTAs were detected at baseline. Azacitidine did not change the number of CTAs expressed, but it significantly increased or decreased expression in nine and five CTAs, respectively. TFDP3 and DDX53, emerged as the main candidates for immunotherapeutic targeting, as they showed three main features: i) a significant derepression on day +28 of cycle one in those patients who achieved complete remission with hypomethylating treatment (FC = 6, p = .008; FC = 2.1, p = .008, respectively), ii) similar dynamics at the protein level to what was observed at the RNA layer, and iii) to elicit significant specific cytotoxic immune responses detected by TFDP3 and DDX53 HLA-A*0201 tetramers. Our study addresses the unmet landscape of CTAs expression in MDS and CMML and revealed a previously unrecognized TFDP3 and DDX53 reactivation, detectable in plasma and able to elicit a specific immune response after one cycle of azacitidine.
